With summer heat coming into full swing, a lot of us are heading toward the fiery summer inferno without the comfort of air conditioning, like Lifehacker reader Josh:

I just read your post on making your own air conditioner, and I have to say that I am quite impressed! My problem is that my car's AC is dead and I don't have the cash to get it fixed. Do you or your readers have any suggestions on cooling down my ride during the hot Texas summer?

Since I don't have an air conditioner in my apartment, I'm going to piggyback on Josh's question here and ask: What are your favorite A/C-less, stayin' cool summer tips? Let us know in the comments or at tips at lifehacker.com.
